摘要：
A rectangular wave generator includes a comparator having a first input terminal receiving an input signal, a second input terminal, and an output terminal. The comparator slices the input signal at a hysteresis voltage so that a rectangular wave is output via the output terminal. The generator also includes a differentiating circuit connected between the output terminal and the second input terminal. The differentiating circuit functions as a feedback circuit. In lieu of the differentiating circuit, it is possible to use a feedback circuit connected between the output terminal and the second input terminal, the feedback circuit comprising a control unit for changing a feedback quantity of the differentiating circuit in accordance with variations in a frequency of the input signal.
